To Match Setup Values in Drawings and Formats
Like a drawing file, a format file retrieves default values from a .dtl setup file.  If you want your format .dtl file to have the same values as your Detail options file, you can retrieve the Detail options file into the format.
With the format file open:
1. Click File > Prepare > Drawing Properties, and click change against Detail Options.
2. The Options dialog box opens.
3. Click to open the target .dtl file. Only those options that are valid for formats are read.
4. Click OK.
